Hard to believe, but articles are popping up at business websites claiming that venerable Hewlett-Packard may fail. In their most recent fiasco, HP wrote off a loss of $8.8 of their $11.1 US billion acquisition of Autonomy and have alleged fraud in the deal. Revenue is down 7% from a year ago and the stock has hit a 10-year low. The company is laying off 27K employees but that may not be enough. Some speculate HP might be broken up into parts with buy-outs involved. This article from last May offers a good in-depth analysis of how all these problems came to pass.

Nokia is kind of different from the others you mentioned; in their case, they didn't just decide to go Microsoft-only. Mr. Head Dumbass Elop made the braindead decision to practically throw everything they had out and switch to Microsoft overnight. No sane businessman with any respect for his company or even his own public image would do that. I am still shocked at such a ridiculous move.

Series 40 OS is almost flourishing under Elop, finally rapidly moving forward after over half a decade of total stagnation. It's even starting to be described as a smartphone platform now (arguably, if we were to use any resemblance of rigorous definition, it was always more a smartphone than the iPhone in its first year). Series 30 handsets also undergo changes, advancements.

But I guess by now I'm not shocked that many critics don't really follow what Nokia did and is doing...
